Warning - so far this is only for advanced users
Will be simplified with the release of a helper program, but for now, this is how it's done:
If you don't understand it, please wait then =3

Note: Sometimes the hex editors "don't save to memory stick correctly" - so I suggest hex editing on the
	Hard drive and then copying the edited file to seplugins.
	What happened to me was that Hex Workshop would save, but then I would unplug & replug the PSP ... only to see that my edits weren't saved

1) How to Change the SAVE GAME MAC (without the need of flashing)
	a) Open up NitePR.prx in a hex editor
	b) Search for the string "CFG"
	c) One should see "CFG" followed by a 0x88 ... the "magic header"
	d) Now after this one should see a NULL byte and 6 0xFFs
	e) Set the NULL byte to anything that's not 0, e.g. you can set it to 0xFF or 0x01 (this notifies NitePR.prx that we're using a custom MAC)
	f) The 6 0xFFs is where one would put his/her custom MAC address
	Note: The MAC address here only affects savegames, and not the MAC address that's used to go online

2) How to Change the Buttons
	a) Open up NitePR.prx in a hex editor
	b) Search for the string "CFG"
	c) One should see "CFG" followed by a 0x88 ... the "magic header"
	d) Now after this one should see a NULL byte and 6 0xFFs
	e) After the 6 0xFFs should be TWO dwords, 00 00 80 00 and 00 00 30 00
	f) The first dword is the "on/off KEY combo"
	g) The second dword is the "menu KEY combo"
	h) To generate the key combo value, use this chart:

	PSP_CTRL_SELECT     = 0x000001
	PSP_CTRL_START      = 0x000008
	PSP_CTRL_UP         = 0x000010
	PSP_CTRL_RIGHT      = 0x000020
	PSP_CTRL_DOWN       = 0x000040
	PSP_CTRL_LEFT       = 0x000080
	PSP_CTRL_LTRIGGER   = 0x000100
	PSP_CTRL_RTRIGGER   = 0x000200
	PSP_CTRL_TRIANGLE   = 0x001000
	PSP_CTRL_CIRCLE     = 0x002000
	PSP_CTRL_CROSS      = 0x004000
	PSP_CTRL_SQUARE     = 0x008000
	PSP_CTRL_NOTE       = 0x800000
	PSP_CTRL_SCREEN     = 0x400000
	PSP_CTRL_VOLUP      = 0x100000
	PSP_CTRL_VOLDOWN    = 0x200000

	i) Pick the keys and then OR them together
	   e.g., if I want PSP_CTRL_VOLUP + PSP_CTRL_VOLDOWN, that would be:
	   0x100000 | 0x200000 = 0x300000
	J) Finally, the last step is to reorder the bytes based on endianess, and save em to the right spot
	   0x300000 "reordered" would become "00 00 30 00" ... notice what the SECOND DWORD is? It's already "00 00 30 00"! =3
